Application filed June 29, 1916.

To all whom it may concern:

Be it known that 1, WILLIAM E. HILL, a citizen of the United States, residing in the city of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented an Improved Brooder, of which the following is a specification.

My invention is an improved brooder designed to effect more uniform, efficient and economical heating than has obtained in prior constructions, to protect the flame of the lamp from the influence of drafts so that it can be relied on to burn steadily, and to provide a simple, strong and convenient structure. I

My invention is illustrated in the accompanying drawing showing my improved brooder in vertical section.

My improved brooder, as illustrated in the drawing, comprises a chamber 1 having a door 1 adjacent to its floor 1 the floor supporting a lamp 2 which may be readily inserted, adjusted in position and removed through the doorway. The chamber is supplied with fresh air through orifices 1 in the wall thereof and waste gases escape therefrom through the port l above which is disposed a hood or cap 1 A chick chamber or room 3, separated from the chamber 1 by the partition 3, contains the hover at provided with the usual curtains 45 for the hovering chamber. A heating chamber 5, located above the hovering chamber and separated therefrom by the partition 4, contains a chamber 6 suitably supported by braces 7, the bottom of the chamber 6 being concave and forming a spreader or hood 6 A flue for hot gases from the lamp provided by the vertical duct 8 (having the removable cap 8) disposed in the chamber 1 the horizontal duct S connected with an in termediate section of the duct 8 and passing through the partition 3 and chambers 3 and 5 to the interior of the chamber 6; the vertical duct 8 leading from the chamber 6 through the chamber 5 to the chamber 8; and the horizontal duct 8 connected with the duct 8* and passing through the chamher 3, partition 8 and chamber 1 into communication with the vertical drum 8 supported in the chamber 1 concentrically with the duct 8 by the brackets 1, the drum 8 being closed at its top by the removable cap 8" and open at its bottom. A drum 9 1s vertically disposed in the chamber 1 so as to contain the duct 8 and be contained in the Specification of Letters Patent.

drum 8, making a close fit at its bottom with the duct 8 and having its top closed by the detachable cap 9. A duct 9 passes from the atmosphere through the chamber 1 and drum 8 to the lower part of the drum 9 and an intermediate part of the latter is connected with a duct 9 which extends through the parts 8 and .3 to a point within the chamber 5 beneath the spreader 6, the duct 9 surrounding the duct 8 A ventilating port'lO in the top of the chamber- 5 is controlled by a valve 11 which is carried by a counter-weighted lever 12 adapted to rock on the fulcrum 13, the position of the lever and valve being adjusted by a thermostat 1 1 connected with the lever by the adjustable rod 15.

It will be understood from the foregoing description that gases from the burning lamp and heated air flow through the passages 8, 8 6, 8 8, and 8 back into the bottom of the chamber 1, whence they escape upward through the port 1, Fresh air to support combustion is admitted to the bottom of the chamber 1 through the ports 1 disposed above the bottoms of the parts 8 and 8 whereby the flame is protected from the influence of direct air currents.

The full effect of the heat generated is utilized in heating air introduced (by he duct 9) to the drum 9, which is heated internally and externally by the hot gases within the ducts S and 8 the air thus heated flowing through the section 9 surhood 6 the chamber 6 providing a pocket of hot gases to effect further heating.

Having described my invention, I claim:

1. A brooder comprising a lamp chamber, a chick chamber, a hover in said chick chamher having a heating chamber connected therewith, a spreader in said heating chamber, a flue extending from an inlet in said lamp chamber through said chick chamber and heating chamber to an outlet in said lamp chamber, and a fresh air conduit extending through said lamp chamber and chick chamber into said heating chamber under said spreader.

2. A brooder comprising a lamp chamber and a chick chamber, a hover provided with a heating chamber in said chick chamber, a

heating flue extending from an inlet in said 1 lamp chamber through said chick chamber and heating chamber to an outlet 111 said lamp chamber, and a fresh air conduit surrounding said flue and extending through said lamp chamber into said hover.

3. A brooder comprising a heating flue having an upright inlet section open at the bottom, an upright outlet section with a bottom opening surrounding said inlet section, and a section in the form of a loop connecting said inlet and outlet sections; in combination with a fresh air conduit having an upright section surrounding said inlet section within said outlet section and a section surrounding part of said third named flue section; and a hover provided with a chamber and a hood in said chamber through which said flue extends and within which said conduit discharges.

4. A brooder comprising a chick chamber, alamp chamber connected with said chick chamber, said lamp chamber provided with a fresh air inlet and a waste gas outlet; a

flue having a vertical section with a closed top and an open bottom in said lamp chamber, a second vertical section having a closed top and an open bottom surrounding said section first named, and a section connecting the inner and outer sections aforesaid; in combination with a fresh air duct having a section in said lamp chamber surrounding the interior and surrounded by the exterior sections of said flue; a duct connecting said duct first named with the atmosphere; a duct connected with said duct first named and surrounding part of the third named section of said flu and a heating chamber through which said flue section third named extends and into which said duct third named discharges.

In testimony whereof I have hereunto set my name this 20th day of June, 1916.

WILLIAM E. HILL.
